[SOLVED] USB Front Panel breaks on 4.11.2

I've got a USB 3.0 front panel hooked up to a PCI-E USB 3 controller (to get an extra header, the panel is basically a hub) that was working semi-reliably on 4.10.x (it had some issues on some boots) and not at all on 4.11.2. The PCI-E card is a "Fresco Logic FL1100 USB 3.0 Host Controller (rev 01)", and there's a set of repeated errors during boot in the kernel log:
"[ 77.273371] xhci_hcd 0000:08:00.0: ERROR mismatched command completion event
[ 82.392953] xhci_hcd 0000:08:00.0: ERROR mismatched command completion event
[ 84.526125] xhci_hcd 0000:08:00.0: Error while assigning device slot ID
[ 84.528675] xhci_hcd 0000:08:00.0: Max number of devices this xHCI host suppo
rts is 32.".
Nothing else is plugged into the card in the back, just the header going to a USB 3.0 hub, and motherboard provided ports work fine. Any ideas?

You want to report this problem upstream, this seems to be something we can't fix here.

Upon updating to 4.11.3 (and when I finally had time to get enough info to report it) the front panel came back online on reboot. It's a generally flakey USB setup on this computer anyway, so it may have been a transient thing - I rebooted instead of shutting it down and cold booting, which tends to affect it. Marking this [SOLVED] for now.
